Disks are now cleanly unmounted after SELinux automatic re-label
Previously, after SELinux relabel, the *rhel-autorelabel* script started system reboot by running the "systemctl --force reboot" command. Consequently, certain steps required to cleanly unmount the *rootfs* image and deactivate the underlying Device Mapper (DM) device were skipped. To fix this bug, the *rhel-autorelabel* script has been modified to invoke the *dracut-initframs-restore* script before the reboot. As a result, disks are now cleanly unmounted in the described scenario.
